agreed...

I had to add:
    CLIENT_OPTIONS(`Address=0.0.0.0, Modifiers=h')dnl

in order to get past certain peoples 'spam' checks.  However this means the
EHLO is reported as:
  by mail.netbsd.org with SMTP; 30 Jul 2003 17:12:48 -0000                      

It would be much more useful to report:
	[213.122.125.148] snowdrop.l8s.co.uk
after all putting in a string that the other end can determine is fairly
pointless.  So the ONLY purpose of the EHLO string is for logging.
If people start checking it, then the spammming software would just
arrange to get it right.  Since it isn't checked they don't bother.
